SPECIFICATION kforming` part of Letters Patent No. 776,237, dated November 29, 1904.

Application filed February 12, 1904. Serial No. 193,224. (No model.)

To all zoll/07W it Wbay concern:

Be it known that I, JoHNR. GREENWOOD, a citizen of the United States, residing' at Boothwyn, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Dyeing-Machines, of which the following is a specification.

This invention relates to mechanism for dyeing wherein the material to be dyed is continuously submerged within the dye without exposure to the atmosphere duringthe dyeing process. Heretofore the material had to be passed several times through themachine, and at each removal for another passage the material was for an extended time exposed to the atmosphere, which is very injurious to the process. In this machine the mechanism is supported upon a framework removably inserted in the vat and passes the material through the machine in return and continuously-repeated courses while immersed in the dye until the requisite color or shade is obtained, with a saving of time, labor in handling, and with uniform excellence in results.

The construction of the machine while capable of continuing the material within the dye throughout the process, except for a very limited time, occupies no more space than the previous machines and can readily be installed in the same position, which is a decided advantagefor plants already established.

The invention is illustrated in the accompanying drawings, wherein similar parts are indicated by similar characters of reference, in which* Figure lis a longitudinal section on line X X, Fig. 2. Fig. 2 is a transverse section on line V V, Fig. l. Fig. 3 is a plan view of the guide-plate at the driving end of the machine. Fig.l 4. is a plan view of the guideplate at the opposite end of the machine.

The machine is removably suspended in a vat l, the vat preferably having the usual means (not shown) for heating the dye liquid, as has been the practice heretofore. The machine has a framework 2, suspended within the vat l by lugs 3, so that it can be lifted out, and carries top rollers 4. 5 6 and bottom rollers 7 8 9, reaching across between the sides of frame 2, the rollers being submerged below the top l0 of the dye liquid. The warp material 11 comes from above the machine and is carried at iirst under roller '7, up and over roller 5, down and under roller 8, up and over roller 6', down and under roller 9, thence through opening l2 in guide-plate 13, preferably of porcelain, to and between the driving'- roller 14, which is provided with a tight pulley l5 and a loose p ulley 16 or equivalent means for its driving, and the pressure-roller 17, which is provided with levers 18, fulcrumed at 19, bearing on boxes 20 and carrying weights 2l or equivalent pressure means. 'lhence it is returned to the opposite end of the machine by passing down and under guide-roller 22, over carrier-roller 23, under guide-roller 24, up through opening 25 in guide-plate 26, also preferabl y of porcelain, which deflects the material to one side, as seen in Fig. 2, and thence over roller 4 down to roller 7, which completes one return-circuit. The next circuit from roller 7 is parallel to the first one until passing roller 9, when the material passes through opening 27 in guide-plate 13, over roller Q8, between rollers le 17, and onto guide-plate 26, through its opening 29 to guide-roller 30 and rollers 4L 7, completing the second return-circuit, and so on -continuously in as many parallel return-circuits as are necessary for perfect results with the dye and material employed in the process.

When dyeing wai-ps, which in some instances are composed of as many as two thousand ends, great care must be exercised to prevent their becoming' tangled and brokenhenee the spreading and separating the material, as illustrated, at one end of the machine by means of the rollers 24 30 and guide-plate 26 and at the opposite end by means of roller 14 17 at A to enter the wash-tank, (not shown,) which may be of the usual or any suitable construction adapted to the purpose.

The machine is illustrated as when using` two warps or pieces of material, each making six return-circuits; but the number of warps or pieces run at once and the number ot' return-circuits made by each can be varied to suit needed conditions or the capacity of the machine, which is only limited by the length of its rollers.

I claim 1. In a dyeing-machine, in combination, a dye-vat, a framework removably suspended therein, having a series of top and bottom rollers, a driving' and a pressure roller to draw the material to be dyed over the rollers aforesaid, guide-rollers to pass the material back for successive passages, and guide-plates having' oset openings or passages whereby adjacent courses of the material may be separated, and
